Thats great...im not saying u wouldnt gain power, im just saying you would be better off with smaller tubing. You have larger exhaust than some motors coming from the factory that are twice the cubic inches.

@shoppy16

I moved from smaller tubing and gained horsepower. I don't know what more proof you want from me. Cubic inches doesn't = needed exhaust flow. It's how much air you can intake first... and then how much exhaust you can get rid of next. The K series cylinder head allows you to do a LOT of both.

[shoppy16]

In some cases smaller exhaust tubing is preferred. Typically 4 cylinders do not require 3 inch exhaust unless making big power. Hell even most v8s dont need 3 inch exhaust. The reason is hot air flows quicker than cooler air, and with smaller tubing the exhaust gets hotter an thus flows faster and more efficiently. Larger tubes mean more airflow, but cooler temperatures. IMO neither car needs 3 inch exhaust.

@shoppy16

Proof is in the pudding sir, 3" exhaust put gains on top of 70mm exhaust. it is better, period. You don't need to explain exhaust to me i know velocity adds power, but also you need the volume to flow enough air for your engine. In the case of my engine, 3" exhaust gained power... not just up top but EVERYWHERE.  I'm talking low cam, AND high cam.

That si is amazing! if they were both stock, the si would be no match for that honda v6

@posvibration21

That other Honda is a 4 cylinder, not a V6.

Congrats on being pretty stupid. You don't hear vtec engage because i was already in vtec when the race started.

[pundit116]

Knocking on the window and trying to scream to get his attention when you have a horn was the greatest part of this vid!!!

@MultiChicklets All of what shit? He has a handful of basic bolt-on parts. It's still a heck of a lot cheaper than an S2K. lol.
